Magika-backed MIME detector integration for qubit-mime.

Overview

Qubit Magika provides MagikaMimeDetector, a qubit_mime::MimeDetector implementation backed by Google's Magika model. It keeps Magika and ONNX Runtime dependencies outside qubit-mime, while still allowing applications to register Magika as a detector provider.

The crate enables bundled-onnxruntime by default so ordinary builds can link and run without a separately installed ONNX Runtime. Disable default features if your application provides ONNX Runtime through another linking strategy.

Installation

[dependencies]
qubit-config = "0.12"
qubit-mime = "0.3"
qubit-magika = "0.6"

Quick Start

use qubit_magika::MagikaMimeDetectorProvider;
use qubit_mime::{
    CONFIG_MIME_DETECTOR_DEFAULT,
    MimeConfig,
    MimeDetectorRegistry,
    MimeError,
};

fn main() -> Result<(), MimeError> {
    MimeDetectorRegistry::register_default(MagikaMimeDetectorProvider)?;

    let mut raw_config = qubit_config::Config::new();
    raw_config.set(CONFIG_MIME_DETECTOR_DEFAULT, "magika")?;
    let config = MimeConfig::from_config(&raw_config)?;

    let detector = MimeDetectorRegistry::default_registry()?.create_default_box(&config)?;
    let mime_type = detector.detect_by_content(b"#!/usr/bin/env python3\nprint('hello')\n");

    assert_eq!(Some("text/x-python".to_owned()), mime_type);
    Ok(())
}

Notes

MagikaMimeDetector delegates filename-only detection to qubit_mime::RepositoryMimeDetector. Content, reader, and file detection use Magika inference, then return Magika's MIME type mapping.
